Circumstances:
The aircraft departed Monterrey-General Mariano Escobido Airport at 0315LT on a flight to Toluca, carrying five passengers and two pilots. Few minutes later, while cruising at 28,700 feet via radial 163, the aircraft went out of control, dove into the ground and crashed in a mountainous area located near Iturbide, in the south part of the Parque Natural Sierra de Arteaga, some 100 km south of Monterrey. Debris were found scattered on an area of approximately 300 metres and all seven occupants were killed, among them the American-Mexican singer Dolores Jenney Rivera, aged 43. She was accompanied with her impresario and members of her team. They left Monterrey after she gave a concert and they should fly to Toluca to take part to a TV show.
Probable cause:
The exact cause of the loss of control could not be determined. However, it was reported that the pilot aged 78 was not allowed to conduct commercial flight due to his age. Also, the young copilot aged 21 did not have a type rating for such aircraft.

Circumstances:
The pilot, who was undertaking training toward a Grade 2 Agricultural Pilot Rating, began work at approximately 0625 hours on the day of the accident. The pilot and his instructor, who was in another topdressing aircraft, flew to a block of land to the south east of Rotorua where the pilot completed 15 sowing runs, while his instructor worked in the local vicinity in the second aircraft. The pilot and instructor completed the work on this block, had a break and then transited to the Waikite Valley, arriving at approximately 0945 hours. At 1045 hours, after refuelling his aircraft, the pilot commenced sowing a ‘special mix’ fertiliser, in an alternating pattern between the instructor and pilot, with two aircraft operating from the airstrip. The alternating pattern allowed the instructor to observe and supervise the pilot during the take off and landing phases, while allowing the operation to proceed efficiently. The pilot and instructor stopped for lunch after an hour of flying, refuelled once more and then continued with their work. The amount of fertiliser that was loaded into the pilot’s aircraft was progressively increased as the work proceeded. The initial load of product was 900 kg, gradually increasing by 50 kg increments, when the instructor was satisfied that the pilot’s performance allowed this increase. The last five loads carried prior to the accident were each 1100 kg. Nothing untoward was noticed during the sowing runs, apart from the pilot aborting one landing attempt, due to the wake turbulence from the instructor’s aircraft during take off. At the time of the accident the pilot was performing ‘clearing runs’, sowing on remaining areas of land not already covered by previous sowing runs. Immediately prior to the accident, the pilot called the instructor on the radio to enquire of his location. The instructor responded with “directly behind you on the other side of the woolshed”. A few seconds later, as the instructor approached to land at the airstrip, he observed the pilot’s aircraft flying in a westerly direction at approximately 400 ft AGL. He then saw the pilot’s aircraft make a slight turn to the left. Describing what he had seen as: “he started to climb and turn slightly to the left, then the plane was in a left hand spin”. The instructor thought at the time that the aircraft spun for one and a half rotations to the left, prior to being obscured by the ridge adjacent to the airstrip. The accident occurred in daylight, at approximately 1315 hours, at Waikite Valley, Rotorua, at an elevation of 1460 ft. Latitude S 38° 18.5', longitude E 176° 17.42'.
Probable cause:
Conclusions
- The pilot was appropriately licensed and held a valid medical certificate.
- The aircraft had been appropriately maintained and no technical discrepancy was discovered that could have contributed to the accident.
- It is likely that, during a climbing turn, the pilot inadvertently allowed an aerodynamic stall to occur at which point the aircraft suddenly departed controlled flight.
- No emergency jettison of the hopper contents was attempted.
- The height above the ground, was insufficient for the pilot to perform a successful recovery once the departure from controlled flight had fully developed.
- The pilot’s lack of experience with agricultural operations and relative unfamiliarity with the aircraft type could not be eliminated as having a bearing on the accident.

Probable cause:
The crew filed a flight plan with an incorrect flight level (FL) and routing. Contributing causes are given as the weather and lack of situational awareness among the aircrew. The inquiry further found the lack of an aircrew pre-flight briefing was a key issue and that unnecessary time pressure and insufficient flight planning also played a part. The aircrew did not adhere to standard checks and procedures and failed to do a proper risk assessment.

Circumstances:
The airplane was substantially damaged during an in-flight encounter with weather, in-flight separation of airframe components, and subsequent impact with the ground near Wells, Texas. The private pilot, who was the sole occupant, was fatally injured. The airplane sustained impact and fire damage to all major airframe components. The aircraft was registered to H-S Air LP and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a business flight. Instrument meteorological conditions prevailed for the flight, which operated on an instrument flight rules (IFR) flight plan. The flight originated from the West Houston Airport (IWS), Houston, Texas, about 2040 and was bound for the Richard Lloyd Jones Jr. Airport (RVS), Tulsa, Oklahoma. Witnesses near the accident site reported hearing an explosion and then seeing a fireball descending through the clouds to the ground. Radar track data for the last portion of the flight depicted the airplane on a 7720 transponder code. The track showed the airplane initially on a heading of about 20 degrees at 23,000 feet. The track continued in this direction until 2120:03.73 when the airplane began a right turn. The right turn continued for about 30 seconds during which time the altitude remained constant and the heading changed to about 90 degrees. After 2120:45.86, the track showed an erratic steep descent that continued to the end of the data. The final data location was received at 2122:15.53 at an altitude of 2,800 feet. The accident location was 0.86 miles and 94 degrees from the last recorded radar position.
Probable cause:
The pilot’s decision to continue the flight into an area of extreme weather, which led to the in-flight encounter with a thunderstorm and structural failure of the wings and tail.

Circumstances:
The aircraft impacted terrain following an in-flight breakup near Shaver Lake, California. The private pilot/registered owner was operating the airplane under the provisions of 14 Code of Federal Regulations Part 91. The pilot and passenger sustained fatal injuries. The airplane sustained substantial damage during the accident sequence, and was partially consumed by postimpact fire. The cross-country flight departed Salinas Municipal Airport, Salinas, California, at 1837, with a planned destination of Eppley Airfield, Omaha, Nebraska. Visual meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan had been filed. The pilot was the son of the passenger. Both had spent the weekend attending a driving academy at the Laguna Seca Raceway, having arrived in the accident airplane earlier in the week. According to the pilot's wife, they had encountered strong headwinds during the outbound flight from Omaha, and had decided to take advantage of tailwinds for the return flight that night, rather than stay in a hotel. The pilot planned to return his father to Omaha, and then fly to his residence in Missouri the following day. Radar and voice communication data provided by the Federal Aviation Administration (FAA) revealed that prior to departure, the pilot was given an IFR clearance to Omaha, and that during his interaction with clearance delivery personnel he read back the clearance correctly. A few minutes after departing Salinas the airplane was cleared to fly direct to the Panoche VORTAC (co-located very high frequency omnidirectional range (VOR) beacon and tactical air navigation system). The airplane followed a direct course of 60 degrees; reaching Panoche at a mode C reported altitude of 17,200 feet, about 14 minutes later. The airplane continued on that course, reaching the Clovis VOR at 1912, coincident to attaining the pilots stated cruise altitude of 27,000 feet. The pilot reported leveling for cruise, and flying direct to Omaha. The sector controller reported that the pilot should fly direct to the Coaldale VOR and then to Omaha, and the pilot responded, acknowledging the correction. For the next 5 minutes, the airplane continued at the same altitude and heading, with no further transmissions from the pilot. The airplane then began a descending turn to the right, with a final mode C reported radar target recorded 60 seconds later. During that period, it descended to 22,600 feet, with an accompanying increase in ground speed from about 190 to 375 knots. For the remaining 6 minutes, a 6.5-mile-long cluster of primary targets (no altitude information) was observed emanating from the airplane's last location, on a heading of about 150 degrees. Following the initial route deviation, the air traffic controller made five attempts to make contact with the pilot with no success. Throughout the climb and cruise portion of the flight, the airplane flew directly to the assigned waypoints with minimal course variation, in a manner consistent with the pilot utilizing the autopilot.
Probable cause:
The pilot's failure to regain airplane control following a sudden rapid descent during cruise, which resulted in an in-flight breakup. Contributing to the accident was the pilot's decision to make the flight with a failed vacuum pump, particularly at high altitude in night conditions.

Circumstances:
The twin engine aircraft departed Paris-Le Bourget Airport around 1500LT bound to Boufarik Air Base near Algiers, carrying a crew of five, one employee of the National Bank of Algeria and a cargo consisting of fiduciary papers intended to the manufacture of bank notes. While cruising at FL150, the crew encountered icing conditions and elected to gain height. While climbing, the aircraft entered an uncontrolled descent, partially disintegrated in the air and eventually crashed in a field located in Saint-Germain-du-Teil, some 20 km east of Mende. The aircraft was totally destroyed and all six occupants were killed.
Probable cause:
In a report published in January 2013, the French BEA confirmed that the accident was the consequence of an excessive frost accretion on all surfaces and airframe of the airplane. Investigations were able to determine that the aircraft was flying at the limit of its performances in adverse weather conditions with dangerous phenomena such as the accretion of clear ice. This situation caused the frost alarm to activate, and the pilots to increase their altitude. At this moment, the airplane entered a spin and the tail detached due to aerodynamic forces that exceeded its certification/design. Out of control, the aircraft completed several barrels before breaking up and descending to the ground.

Circumstances:
The airplane was destroyed when it collided with tree-covered terrain and incurred a postcrash fire and explosion about 19 miles west of Willow, Alaska. The airline transport rated
pilot, who was the only occupant, was fatally injured. The airplane was registered to Fuel Services, LLC, Anchorage, Alaska, and was being operated as a 14 CFR Part 91 visual flight rules (VFR) cross-country fuel transport flight when the accident occurred. Marginal visual meteorological conditions were reported at the airplane's point of departure. The accident flight originated from the Wasilla Airport, Wasilla, Alaska, about 1520, en route to the Nixon Fork Mine, about 28 miles northeast of McGrath, Alaska. According to the co-owner of the airplane, the purpose of the flight was to transport approximately 900 gallons of diesel fuel to a company owned tank that supplies fuel for a mining operation. When the airplane did not arrive at its destination, the co-owner of the airplane reported it overdue to the Federal Aviation Administration (FAA) at 1757. After being notified of the overdue airplane, personnel from the 11th Air Force's Rescue Coordination Center initiated a search for the missing airplane along its supposed route of flight. On the morning of October 16, an Air National Guard C-130 Hercules was able to locate the wreckage. Rescue personnel aboard a HH-60G helicopter were able to reach the site later that morning, and confirmed the pilot was deceased. Two witnesses reported seeing the airplane fly over their locations. The first witness saw the airplane as it was flying northwest at an altitude that he estimated at 3,000 to 4,000 feet under an overcast layer. He stated that the airplane did not sound "normal," but he did not notice anything unusual, like smoke, trailing the airplane. The second witness stated that he saw the airplane fly over his cabin headed southeast at an estimated altitude of 300 to 400 feet. He stated that the airplane sounded like it was "struggling," but he could not see anything abnormal about the airplanes appearance. Primary radar data taken from the Anchorage Terminal Radar Approach Control Facility (TRACON), shows an unidentified aircraft, believed to be the accident airplane, depart the Wasilla airport about 1522. After departure, the track proceeded to the Northwest with cruising ground speeds of between 180 and 193 knots. No altitude or transponder code data was transmitted by the airplane. Around 1343 the radar track changed direction and proceeded to the southeast. Ground speeds after the track changed direction started at 143 knots, and gradually decreased to a low of 117 knots about 5 minutes before the accident. The last radar plot for the airplane was at 1556:47, approximately 5.5 nautical miles from the accident site, and showed a heading of 088 degrees, and a ground speed of 175 knots.
Probable cause:
The pilot’s loss of control of the airplane for reasons that could not be determined because the wreckage was not recovered from the accident site.

Circumstances:
The privately owned SOCATA TBM 700N (registration C-FBKK, serial number 621) departed from Ottawa/Carp Airport, Ontario, on an instrument flight rules flight plan to Goderich, Ontario. Shortly after takeoff, the pilot and sole occupant altered the destination to Wiarton, Ontario. Air traffic control cleared the aircraft to climb to flight level 260 (FL260). The aircraft continued climb through FL260 and entered a right hand turn, which quickly developed into a spiral dive. At approximately 1219 Eastern Daylight Time, the aircraft struck the ground and was destroyed. Small fires broke out and consumed some sections of the aircraft. The pilot was fatally injured. The 406 MHz emergency locator transmitter on board the aircraft was damaged and its signal was not sensed by the search and rescue satellite-aided tracking (SARSAT) system.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The pilot lost control of the aircraft for undetermined reasons and the aircraft collided with terrain.
Findings as to Risk:
1. Operating an aircraft above 13 000 feet asl without an available emergency oxygen supply increases the risk of incapacitation due to hypoxia following depressurization.
Other Findings:
1. The avionics system had the capability to record data essential to the accident investigation but the recording medium was destroyed in the accident.
